CUTTING AND RAVELING MACHINE FOR Rue MATERIALS.

SPECIFICATION formingpart of Letters Patent l\ To. 663,210, dated December 4, 1906.

Application filed September 16, 1897. Serial No. 651,846. (No model.)

cutting of the material into strips by the same f machine and during the same operation which does the raveling.

A further object is to provide adjustable means for operatively connecting the parts of the machine together; and a further object is to provide saws and improved guide, all as more particularly set forth in detail below.

In the accompanying drawings, forming a part of this specification, Figure 1 is aplan of the machine; Fig. 2, an elevation of Fig. 1 looking from a point above Fig. 1, showing the adjustable gears connecting the working.

parts of the machine; Fig. 3, a broken elevation of some of the parts shown in Fig. 1 looking from a point at the right and showing a portion of the guide in section and other parts broken away; Fig. 4, a sectional elevation on line c in Fig. 1 andlooking from a point at the left and on line e e in Fig. 2 looking from a point at the right and showing the operation of both saws on the edges of the rug material; Fig. 5, an enlarged detail of one of the gear-adjusting arms, shown dotted in,

Fig. 2; and Fig. .6 is a section on line 1: in Fig. 5 looking from apoint above.

Referring to the parts of the drawings pointed out by numerals, 7 and 8 are portions of the machine-frame in which the two outter-shafts 10 and 11 and the two roller-feed shafts 27 and 28 have bearings, Figs. 1, 4, and 6. The cutters or revolving knives 13 and 14 are one above the other and act on the material 15 like a shear, as shown in Figs. 1 and 3. The feed-rollers 16 and 17 are also one above the other a little in advance of the knives, Figs. 1, 3, and 4. By each side of the feed-rolls 13 and 14 are the saws 18 and 19, one on each side, as in Fig. 4, in position to act on the material and ravel it at each edge, as shown in 20 and 21,which are at right angles to the feedroller shafts and have bearings in a branch portion 22 of the frame. The bearings of the saw-shafts may be like those in Fig. 4 at 23 and 24, so as to adjust the saws nearer together or farther apart by turning the screws 25, or the bearings may be plain, as at 26 in Fig. 1, and have no provision for adjustment.

One of the purposes of adjusting the shafts which carry the raveling-saws is to control the depth of raveliug desired to be performed.

On the outside of portions of the main frame and attached to the ends of the rollerfeed shafts are gears 29 and 30. The gear 29 is attached to the shaft 27, and the gear 30 is attached to the shaft 28. To the same ends of the cutter-shafts 10 and 11 are attached like gears 31 and 32, as in Fig. 2. The gears 31 and 32 are connected by intermeshing gears 33 and 34. The lower feed-roller gear 30 is connected with the lower cutter-shaft gear 32 by a gear 35, and the upper feed-roller gear 29 is connected with the upper feed-roller gear 31 by a gear 36. These gears 33, 34, 35, and 36 are idlers and have bearings in adjustable arms hereinafter described. All these gears are indicated in Fig. 2 in an unfinished manner merely to show their relation and position in the machine. Some of them are also shown in Figs. 1 and 4. The adjustable arms are shown dotted in in Fig. 2 at 38, there being four of them; but for a definite showing of'their construction reference should be had to Figs. 5 and 6, where they are shown enlargedthatis,one is shown in said figures and all the others in the machine are like it.

In portions '7 and 8 of the frame rectangu: lar openings 39 are made to receive the bearing-blocks 40, in which bearing-blocks the shafts of the feed-rollers and the shafts of the cutters have bearings, as indicated by dotted lines in Fig. 2 and shown in full lines in Figs. 5 and 6. These bearing-blocks are vertically adjustable in the openings 39, and the adjustability is controlled by the set-screws 41, by which means the feed-rollers and the cutters and their gears may be adjusted as needed The adjustable arms 38 are mounted on the bearing-blocks, as in Fig. 6,between the frame portion 8 and the gears on the shafts of the :said figure. These saws are mounted on shafts cutters and feed-rollers. 7 These gears are dotted in in Fig. 5. The adjustable arms'38 are provided with an elongated slot 42, and the idle gears are attached to said arms by a bolt 43 in said slot, so that said idle gears can be adjusted lengthwise in said arms. The

' portion of the frame 8 is provided with elongated slots 44 at right angles to the adjustable arms 38, and a bolt 45 adjustably attaches the end of the arms to the frame by said bolt passing through the slot in the arm and the slot in the frame portion 8, Figs. 5 and 6, By means of the described provisions the cuttershafts 10 and 11, the feed-roller shafts 27 and 28, and the idler-gears 33, 34,' 35, and 36 can ments'.

and with the gears 31 and 32.

with gears 29 and 30. It will be readily seen that while this adjustment is convenient it might not always be necessary. The frame portion 7 in the actual construction would of course be provided with adjustable bearings for the ends of the shafts 10, 11, 27, and 28, like those at 40, above described. I

At the rear of and in front of the feed-roll ers l6 and 17 isa hollow guide 46, Figs. 1 and 3, said guide being separated where'the saws come, as at 47. This guide has an inclined portion 43 at the delivery end, 'whichis shown in longitudinal section in Fig. 3, and down which incline the strip of material is conoperator from getting his fingers caught between the knives, as he keeps his hands back of this guard. The guide 46 is attached on a plate or shelf 50, the latter of which is 'at-' tached to the frame portion 7.

Upon operating the machine power would be applied to the pulley of one of the sawsh'aftsfor instance, pulley 51 on "shaft 20; but the pulley might of course be on the other saw-shaft; Power would at the same time be applied to one of the cutter-shafts 10 or 11 by means of a pulley attaohed to one of said shafts. The gears 52 and53 transmit power from one saw-shaft to the other, Fig. In Fig. 1 the pulley 100 on thec'utter-shaft 10 shows a convenient means for applying power to the cutters.

In the operation the material 15 is placed on the shelf 50, Figs. 1 and 3, and under the guard 49 and passed on between the knives and into the guide '46 and between the feed- This guard keeps the material straight and smooth, and, what ismore important, it prevents the rollers, at which time the saws act upon each edge of the strip of material, making it fringed on each edge, as at 54, Figs. 1 and 4.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

l. A combined carpet cutting and raveling machine for preparing rug material, comprising, revoluble cutters for severing a strip of carpet, said cutters having gear-connected shafts, and one of them provided with means i for applying power to the cutters; feed-rollers beyond the cutters, between which rollers the severed strip of carpet passes, gear-connected shafts to said feed-rollers and gear all be adjusted to meet the proper require- For instance, when the machine is put togetherthe gears 33 and 34 wouldbe adjusted so as to mesh properly. with each'other Gears 33 and 36 would also be adjusted to properly mosh,

connections between said roll'er shafts and the shafts of the C't1tl3 I'S; raveling-saws one on each side of the feed-rollers, and having geai connected shafts and one of them provided with means for applying power to the ravehhgsaws; and a guide at the contiguous edges of the feed-rollers, and having an opening each side of 'said rollers for receiving the raveling edges of the saws, substantially as set forth. v
